Place turkey in slow cooker stoneware.

In a saucepan over medium heat, combine remaining ingredients except for liquid smoke.

Bring to boil and simmer for 5 minutes.

Remove from heat and stir in liquid smoke.

Pour sauce over turkey.

Cover and cook on LOW for 8 to 10 hours or on HIGH for 4 to 5 hours, until turkey is falling apart.

Transfer turkey to a cutting board and pull meat off the bones in shreds, using two forks.

Return to sauce and keep warm.

When ready to serve, spoon shredded turkey and sauce over warm buns.
